Subject: RE: [LIB] Removing boot password in BIOS
I just downloaded a copy of the 110CT User Guide and looked through it.
Apparently the password prompt can't be disabled in BIOS. But in the 'HW
Setup' options in 'Control Panel' on the 'Security' tab, there's an option
to 'Remove' the password 'Registered' attribute. There seems to be another
method using a 'service diskette' FD.

Shoot... I skipped a step in the procedure of editing the HEX values that
I wrote out in the last message. Here's the full procedure:
From: "Matthew Hanson" <[EMAIL PROTECTED]>
I found this procedure for clearing the password in the archives. Is this
the only way you can removed the thing after it's been set:
================================
This is what you need:
1. Your notebook
2. An empty formatted diskette (720 kb or 1,44 mb)
3. A second computer (e.g. a DOS desktop PC)
4. A hex-editor (e.g. Norton DiskEdit or HexWorks)
This is what you have to do:
1. Start the desktop PC and start the hex-editor
2. Put the disk in drive A:
3. Change the first five bytes of sector 1 (boot sector is sector 0) to:
4B 45 59 00 00
4. Save it! Now you have a KEYDISK
5. Remove the disk from drive A:
6. Put the disk in the notebook drive
7. Start the notebook in Boot Mode (push the reset button)
8. Press Enter when asked for Password:
9. You will be asked to Set Password again. Press Y and Enter.
10. You now see the BIOS configuration where you can set a new password.
================================
After many failed attempts, I finally got the above procedure to work, but
only once. I haven't been able to duplicate the success twice. This is
what I did:
* Did a full format of a FD in my L110 running W98.
* Put the FD in the desktop and edited Sector 1 start to 4B 45 59 00 00
* Put the FD back in the Lib FDD
* Shut W98 to the DOS mode with the FDD attached
* Pushed the reset button.
* After reboot, entered the existing password
* I was in fact finally presented with a prompt to enter a new password.
* I just hit ENTER without adding any characters
* I was returned to the same prompt.
* Hit ENTER again and I think the system restarted
* Was presented with the same prompt for a password
* Entered the old password, and the system booted
But for some reason I was only able to get that process to work once.
Usually I get an "Invalid System Disk" error message after entering a
password when the system tries to boot off of the floppy. That because it
was never made bootable. It just had those HEX values modified to read
'KEY' in ASCII.
I tried making the disk bootable and then modifying the HEX values, but the
system fails to boot off of it complaining that it can't find a file.
The behaviour of being asked for a new password, just hitting ENTER, and
then hitting ENTER again as described above, is the same behaviour I see
when trying to change the password when booting into BIOS/Setup.
Sure could use some feedback on this.
Thanks,
Matt
